The investigations were cared out in summer rape field in experimental station of Aleksandras Stulginskis University (54° 53' 5.95", 23° 50' 36.26") during May – August 2012. 12 metalic delta traps and 4 diferent pheromones have been used for trapping of adults of Plutella xylostella. A total of 427 indivuals were captured. Results showed that numbers of P. xylostella adults caught in pheromone traps were negative correlated with rainfall. Fly activity was highest on the 30 June – 4 July and 14–17 July, when precipitation was in minimum. The experment demonstrated that the first pheromone dispenser with Z11-16:Ald : Z11-16:Ac : Z11-16:OH : Z9-14:Ac mixture of 0,7:0,3:0,01:0,01 was the best. Even 56% of all captured moths have been caught using current pheromone.
